Su-30

Military tungsten alloy cube is usually consisted of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe.  Military tungsten alloy cube has high hardness (25HRC~40HRC),excellent elongation and non-toxicity. The most important property for tungsten alloy cube is that small volume with high density, which means it can be used as counterweight for Su-30.


The Sukhoi Su-30 (NATO reporting name: Flanker-C) is a twin-engine, two-seat supermaneuverable fighter aircraft developed by Russia's Sukhoi Aviation Corporation. It is a multirole fighter for all-weather, air-to-air and air-to-surface deep interdiction missions.

The Su-30 has two distinct version branches, manufactured by competing organisations: KnAAPO and the Irkut Corporation, both of which come under the Sukhoi group's umbrella. KnAAPO manufactures the Su-30MKK and the Su-30MK2, which were designed for and sold to China, and later

Indonesia, Venezuela and Vietnam. Due to KnAAPO's involvement from the early stages of developing Su-35, these are basically a two-seat version of the mid-1990s Su-35. The Chinese chose an older but lighter radar so the canards could be omitted in return for increased payload. It is a fighter with both air superiority and attack capabilities, generally similar to the U.S.F-15E.
